Teaching NVS PGT 2024 Test Series Physics Atoms De Broglie’s Explanation of Bohr’s Second Postulate of Quantisation
An electron (mass m ) with an initial velocity v = v0î(v0 > 0) is in an electric field E = -E0î(E0 = constant > 0). It’s de Broglie wavelength at time t is given by
1
\(\rm \frac{\lambda_0}{\left(1+\frac{eE_0}{m}\frac{t}{v_0}\right)}\)
2
\(\rm \lambda_0\left(1+\frac{eE_0t}{mv_0}\right)\)
3
λ0
4
λ0t.
